Chemical Structure

2-Chloroethanesulfonyl chloride CAS 1622-32-8 chemical structure

Description

Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.

CATO supplies 2-Chloroethanesulfonyl chloride (CAS 1622-32-8), a certified reference material (molecular formula C2H4Cl2O2S, MW 163.02 g/mol) for analytical method development and quality control.

Structurally, 2-Chloroethanesulfonyl chloride (C2H4Cl2O2S) contains a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine substitution. The molecule exhibits a degree of unsaturation (DBE) of 0.0, corresponding to approximately 0 ring(s) or double-bond equivalent(s). With a molecular weight of 163.02 g/mol, it falls into the medium-molecular-weight range. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.

The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
